METALLIC DOOR.

Specification of Letters Patent.

Patented May 3, 1921.

Application led February 8, 1916. Serial No. 76,931.

To all fw hom it may concern Be it known that I, WERNER E. CLARIN, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Metallic Doors, of which the following is a specification.

My invention relates to improvements in metallic doors and the like and has for its object the provision of an improved construction of this character which is simple, capable of economical manufacture and strong and durable in use.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a face view of a door embodying my invention,

Fig. 2, an enlarged partial vertical transverse section of the same,

Fig. 3, an enlarged horizontal section taken on line 3 3 of Fig. 1,

Fig. 4, a vertical section taken on line 4 4 of Fig. 2,

Fig. 5, a perspective view of one end of a bottom rail employed in the construction,

F ig. 6, a perspective view of one end of a locking key employed in the construction,

Fig. 7 a perspective view of the lower end of one of the Stiles employed in the construction, and

Fig. 8, a perspective view of a portion of one of a number of combined panel holders and moldings employed in the construction.

The preferred form of construction as illustrated in the drawings comprises two vertical side Stiles or members 9 and top, intermediate and bottom rails 10, 11 and 12 connecting said stile members. The stile members 9 are hollow sheet metal channel members arranged with their open sides inward and provided with inwardly offsetsecuring portions 9 extending in the same general direction as the sides of said channels. The upper and lower ends of the stile members 9 are partially closed by bending extended portions 13 of said side members inwardly as indicated in Fig. 7, gaps 14 being provided adjacent the inwardly offset securing portions 9 for a purpose which will appear hereinafter, end portions 13 being gas welded together. Both the top and bottom rail members 10 and 12 are in the form of channel members the open sides of which are arranged inward with res ect to the door and the ends thereof provide with inwardly and backwardly bent flanges 15 adapted to rest immediately adjacent and outside of the corresponding offset portions 9. The top of top member 10 and the bottom of bottom member 11 is extended at 12 at each side sulliciently to fill the corresponding gaps 14l and abut against the stile closing portions 13 as indicated in Fig. 4. Locking keys 16 substantially in channel form but having the sides of the channel inwardly offset and provided with outwardly and backwardly turned flanges or lips 17 are arranged to engage and interlock with the portions 9 and the flanges 15 to serve as a means for securing the Stiles and rails together, the heads of the keys 16 being of a width to nicely span the channel members 9, 10 and 12 and fit between the plates constituting member 11 thus greatly reinforcing the construction. The intermediate rail 11 is formed of two transverse plates provided at their ends with the inwardly and backwardly turned flanges 15 adapted to coperate with the corresponding securing portions 9 and be interlocked therewith by means of said locking keys 16, the gaps 14 being provided to facilitate insertion of said locking keys. Combined molding and panel holding members 18 are arranged in substantially channel form and provided at their edges with inwardly and backwardly turned flanges 19 adapted to interlock with the portions 9 and the flanges 15 and 17 thus serving as means for holding said molding members in place. Each of the molding members 18 is provided with a central channel 19 adapted to receive the edges of the lower panel 21 of the door, the upper edges of the lower rail 12 and the lower edges of the intermediate rail 11 being provided with inwardly oifsetportions 9 cooperating with corresponding locking keys 16 to secure the top and bottom moldings in place.

The moldings 22 for the upper panel'of the door are in general channel form having the edges of the channels turned inwardly length of the stiles.

. between the stiles 9 as will be readilyunderstood. YThen the corresponding locking keys l16 are slipped into place interlockingthe ends of intermediate rail 11 with the corresponding securing portions 9', these lockingkeys 16 extendingr substantially the full Then the side moldings are secured in place and the panels inserted therein. The moldings arethen secured to the rails lO'and 12 and said rails placed in position, the portions 12 closing' the gaps -14 and are gas welded to the ends 13 ot the stiles. j Y j v The specific form of interlockinp,` plates provided between the different members are easily assembled, highly eflicient in use and capable ot economical manutacturej, since `the parts or members having; considerable size are very simple, the complicated shapes being;r provided on the locking` keys 16 and the moldings18-22 which areof comparatively small size and therefore capable ot easier machine manipulations. The construction is strong and durable and capable of economical production. Y

While I have illustrated and described the preferred form of construction for carryingv my invention into effect, tbisis capable of variation and modification without depart- Y inf;r from the'spirit ot' the invention. I, there- Vfore, do not wish to be limited to the precise f details of constructionset forth, but desire to avail myself ot such variations and modifications as come within the scope of the ap- VAcui pended claims.

Having described my invention -whatl claim as new and desire to secure by-Letters Patent is:

l. A constructionof the class described,
